Abstract

We present an approach to translate scientific requirements into instrument specifications by using a forward model for generic airborne imaging spectrometers in earth remote sensing. Based on scientific requirements, for each relevant variable detectable using imaging spectroscopy, ground reflectance spectra have been provided by specialists in their field of expertise. Relevant changes to be detected in the observed variable are used to derive critical delta reflectances. Realistic mission scenarios are subsequently combined with theses delta reflectances and a radiative transfer code to determine spectral NedL values at the sensor level. The combination of various fields of application in terms of detectable variables and the use of realistic mission scenarios leads to the determination of various NedL levels that are determined at given at sensor radiances. Using this concept, manufacturable specifications can be derived from scientific requirements.
